anybody willing to give it a try and give me a feedback?

I changed the ASM groestl algo, from generic mmx (opteron) code to core2duo code, which is supposed to be faster and more optimized.
on top, you can compile now with -O3 without complains about the registry numbers in use (r15).

I am doing it from a laptop and mining with it does not change things that much, numbers are not flashy so I am just wondering, building and testing this, if it does  actually improves performances on top high end cpu core2duo or not.
